Diamond Princess had a far higher percentage of older (over 70) people. I also would like to know if the HVAC system is as centralize in a prison as it is on a cruise ship.
The problem is that prisoners routinely share common spaces. It doesn't matter how the air circulates, when they all cook, eat, work, shower, and exercise in the exact same communal rooms.
Combine that with insufficient sanitation, and it's a miracle that only half of them got sick.
I agree that HVAC can cause spread. My point is that prison life does not allow for social distancing, and that the HVAC is irrelevant when everyone is living in essentially the same space.
